X rays, beta rays, and other radiation sources in adequate doses can cause ocular injury. The eyelid is particularly vulnerable to x-ray damage because of the thinness of the skin. Loss of lashes and scarring can lead to inversion or eversion (entropion or ectropion) of the lid margins and prevent adequate lid closure. Scarring of the conjunctiva can impair the production of mucus and the function of the lacrimal gland ducts causing dry eyes. X-ray radiation in a dose of 500-800 R directed toward the lens surface can cause cataracts that, in some cases, will be delayed for several months to a year before opacities appear. Treatment for these injuries consists of appropriate oculoplastic repair of lid deformities and scarring. Tear and mucous deficiencies can be improved with topical artificial tears and evaporation protection in the form of protective glasses with side shields that seal to the face. Radiation cataracts can be surgically removed.
